Dark spots on the skin, age warts, discolourations after inflammations or burns and light, so called café-au-lait spots. These spots can be removed with the help of an Nd-YAG-laser without scars. Malignant, brown skin spots and regular birthmarks can by no means be treated this way.
Health risks would be unclear. Diagnostics must be done before each laser treatment of a pigmented change. Reflected light microscopy (digital dermoscopy) with 40-200x magnification is normally carried out with digital videgraphic documentation. In well-grounded exceptional cases, a so-called shave-histology is carried out.
If there are no doubts that the pigmented change is benign, laser treatment can be carried out. During this treatment, Pigmented bodies (Melanosomen) are permanently destroyed, but the cells remain alive. This procedure does not cause any noteworthy pain.
